Abstract

A radically curable coating composition containing) 50 to 95 parts by weight of an unsaturated polyester component having a viscosity at 23.degree. C. of 1,000 to 15,000 mPa.s, B) 5 to 50 parts by weight of compounds containing (meth)acryloyl groups and/or vinyl ether groups, C) 0.01 to 0.3 wt. %, based on the total weight, of waxes and/or paraffins having a melting point of 35+ to 100.degree. C. and D) 0 to 10 wt. %, based on the total weight, of at least one plasticizer or carbamic acid resin, and the use of the coating composition for coating substrates, in particular wood substrates.
